GoLang 从文件路径中取得目录路径

Go 代码

package main
import (
    "fmt"
    "os"
    "strings"
)
// 从文件路径中取得目录路径
func PathToDir(path string) string {
    if len(path) < 1 {
        return path
    }
    pathRune := []rune(path)
    if os.IsPathSeparator(uint8(pathRune[len(pathRune)-1])) {
        pathRune = pathRune[len(pathRune)-1:]
    }
    path = string(pathRune)
    tmp := strings.Split(path, string(os.PathSeparator))
    newPath := strings.Join(tmp[:len(tmp)-1], string(os.PathSeparator))
    return newPath
}
func main() {
    dir := PathToDir("/etc/cron.d/e2scrub_all")
    fmt.Println(dir)
}

输出

/etc/cron.d
